STRESS - STRAIN STATE OF THE LOCAL AREA IN THE BUILDING ELEMENT WITH STRUCTURAL DEFECT

Evaluation of the building element technical state relies on verification calculations using estimated construction material properties. Physical and mechanical properties are predominately by non-destructive test methods. The accuracy these methods is affected level stress-strain structural present defects. variability concrete over time under constant loads a determining factor for durability reliability element. influence physical characteristics deformation process local area adjacent to defect has been investigated. research performed models software systems "LIRA SAPR" "SOLIDWORKS". A model having dimensions 100 x 400 mm was used study. Materials grades C12/15 through C25/30 with corresponding have used. Load parameters modeling varied from 0.1 0.5 ultimate loads. Performed made it possible obtain fields stress, displacement different stress levels.
